_putch, _putwch
Writes a character to the console.
Important
This API cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported with /ZW.
int _putch(
int c
);
wint_t _putwch(
wchar_t c
);
Parameters
- c
Character to be output.
Return Value
Returns c if successful. If _putch fails, it returns EOF; if _putwch fails, it returns WEOF.
Remarks
These functions write the character c directly, without buffering, to the console. In Windows NT, _putwch writes Unicode characters using the current console locale setting.
The versions with the _nolock suffix are identical except that they are not protected from interference by other threads. For more information, see _putch_nolock, _putwch_nolock.
